I've been using Paypal since 1999 and have had absolutely no issues with them.
Actually on a sale overseas, they credited me the payment, then 10 days later debited me because they could not access the foreign bank, then that was resolved and I was credited - twice! Paypal is part of the Wells Fargo Bank, so there is no fooling around. And, if they did sell your private information, then millions of people would have their banking information all over the net, and certainly hacked. This has never happened to me ever. And I am leery of on-line banking, but in over 10 years I have never had any reason to distrust Paypal. And they have phone support, unlike Ebay. The only reason Paypal may delay a payment is due to the funds from the sender not being available. Even a money order can be held by your bank for a few days. They now consider them as being a "check" due to all the fraud going around. That;s what my bank HSBC told me. They won't even accept a "walmart" type money order any more. Just my humble opinion.
